Celestial 𝓌₁₊∞ Symmetries from Twistor Space
We explain how twistor theory represents the self-dual sector of four-dimensional gravity in terms of the loop group of Poisson diffeomorphisms of the plane via Penrose's non-linear graviton construction. The symmetries of the self-dual sector are generated by the corresponding loop algebra 𝐿𝓌₁...
